I just installed OS70 in one of my Fury Experts. Has anyone experience issues when running at ilde or the mixture being too rich or too lean at ilde causing it to shutoff at low idle. This is a new OS70.
I would appreciate any help...

the spool up problem is an air leak fault.i cured mine by sealing the loose fitting carb with silicone around the base.

all comments are my opinion only!

Mine was perfectly sealed I know, I checked several times. If you search on RR you will find an old thread about my OS70 complaints.

I only could fly 8 tanks on a OS#8 plug (I even started to think the #8 on the plug meant that she would be good for 8 flights )

On the 8th flight the same problem appeared over and over... cut out during spoolup.

I played with nitro (10%, 15%, 20%). I played with needles (lean, rich, etc) I played with idle settings (low, high idle), I tried everything.

Finally when I was ready to trash the engine I put an enya #3 in there... I had it for 50 flights without ANY problem until I upgraded to a YS91. No cut outs, no cougth, nothing. A perfect engine.It's now gathering dust on the shelf though...
